I have a Shilen 243 Win Ackley Improved barrel on its way to me. I have not found anywhere that has a head space gauge in stock, despite this not being an obscure chambering.

If someone on this board owns such a gauge and would be willing to sell, rent or loan it so that I can install my new barrel, it would be highly appreciated.

Please send a PM if you can help out. I'm located in SE Michigan.
